It will be apparent that I have provided a means for materially increasing the life of rubberheels. The concavo-convex'cur V vature of wear plate permits its majorpor tion to project above the surface of the heel, and by settingthe plate in a recess formed in the heel, it is possible to avoidreducing the thickness of the edges, at the sametime eliminating any protruding edges which might catch on sharp objects orprojections. Such wearplates may be secure 1y attached to all kinds of rubber'heels in any desired position thereon before the heelsare fastened to the shoes. I After the rubber heel has been placed on the shoe, the wear plate :cannot become loosened. On' the other hand worn out plates may be readily replaced without the services ofshoe rethe. shoe; a by NVhile I have shown in the drawings and have describedherein in detailthepreferred embodiment ofv ;my, invention for the purpose of illustration, it is to be understood that I do not thereby intendlto limit my in-: vention to'the construction shown, butaim 1 vention.

I claim as my invention:

1. The combination with a leather heel lift and a rubber heel secured to said lift, of a wear plate on the tread of said rubber heel, a nut on the under side of said heel, a bolt clamping said heel between said nut and said wear plate and having a fiat-- tened end projecting beyond said nut, and a locking plate secured to said lift opposite said nut and having a slot therein receiving the flattened end of said bolt and thereby locking it'against rotational movement, said heel, when attached to said lift, being adapted to be separated from the lift sufficiently to unlock the bolt and permit removal of said wear plate.

2. The'combination with a leatherheel lift and a rubber heel secured thereto, of a wear plate anda'nut positioned respectively on the outer and inner sides of said heel, a bolt clamping said heel, between said wear plate and said nut, said bolt having a flattenedend pro ecting beyond said nut int'o'said lift, and means providing a recess in saidleather-lift receiving said flattened end, said'recess having sides cooperating with said flattened end to prevent rotation of said bolt, said bolt being removable from said heel when the heel and lift are sepa- 'ratedlsufliciently to withdraw said flattened end from said recess. 7 g
